Abstract: 1,238,084. Making padded bags. SHELDON PAPER Ltd. 10 June, 1970 [16 June, 1969], No. 30372/69. Heading B5D. In making a padded bag comprising inner and outer layers of kraft paper with corrugated paper sandwiched therebetween, the kraft paper is fed from rolls 1 and the corrugated paper is fed from rolls (11, 12, Fig. 6) at right angles to the rolls 1, the corrugated paper being striated longitudinally by rolls (15, Fig. 6) and being cut and fed at spaced intervals by belts 18 to further belts 19, 19a running at right angles to the belts 18. The pieces of corrugated paper are now fed down the length of the machine and the sheets from rolls 1 are fed over and under the corrugated paper by rolls 5 and 11, the lower sheet passing through a printing device 8 and a gluer 10. The sheets then pass to rolls 20, 21 which press together the kraft sheets and may be heated to set the glue applied by the gluer 10 to encapsulate the corrugated paper. A further roll 22 applies glue for the leading edge of each bag length, a crease roll 23 forms a longitudinal crease in the sheets, and a rotary knife 24 cuts the sheets into bag lengths. A plough 25 folds the sheets along a central crease line and a sword 26 flattens the folded sheets. The longitudinal edge of the bag is then glued, turned over, and sealed. A belt 33 conveys the bag lengths at a speed higher than that at which they have been travelling to avoid bunching. A transverse belt conveyer 40 removes the partially completed bags and passes them through means which glues, turns over, and seals the bottom of the bag and finally stacks them in an inclined position from where they are subsequently removed in batches by hand. Small bags may be made in identical runs arranged side-by-side; for larger bags a single run will be provided.

Abstract: 1,257,054. Automatic control systems. HONEYWELL Inc. Jan.10, 1969 [Feb.23, 1968], No.1708/69. Heading G3R. In an automatic control system having a plurality of zones 11-13 each separately and progressively controlled and fed from a common controlled source, each separate control is linked to the common source control to influence it continuously in a direction to meet the changing conditions in the zones. A damper e. g. 30 adjusts the flow of air to a zone 11 the temperature of which is measured by a thermostat 32 controlling a reversible motor 31. When the damper is nearly fully opened a switch 33 is closed shunting one section of a bridge network 41 connected to an amplifier relay 42, permitting current to flow to a motor 43 which opens a valve 20 increasing hot water flow to a heat exchanger 14. When switch 33 re-opens, with switches 33<SP>1</SP>, 33<SP>11</SP> open, the motor 43 runs to gradually close the valve 20. In another arrangement Fig. (not shown) each zone has an individually controlled heat exchanger and the common source has a heater or cooler controlled in a reverse sense to Fig. 1. In a modification, Fig.3 (not shown), the motor 33 may alternatively adjust a resistor in one arm of a second bridge network, a second arm of which has a temperature sensitive resistor situated in the common duct, which second bridge is connected to the input of the amplifier relay 42 included in either Fig.1 or Fig.2.
